New car technical round-up

As the start of the season gets closer, teams are speeding up the development of their cars, with the introduction of new pieces nearly every day. Craig Scarborough looks at the latest innovations

Last week saw the penultimate pre-season test, for most teams in Jerez. Despite it being initially marred by rain, as the weather improved the teams were able to focus on longer runs and introducing new developments.
